Jan 26, 2010: - I used theta as the polar coordinate to parameterize the wire. I did not use any second angle such as phi. I found the vector r-hat by realizing that the projection of the r-vector in the yz plane gives all the information needed for the y and z components. The projection of the r-vector into the xz plane gives all the information needed for the x component of the vector. I drew out these projections and determined how they changed with theta and r'. -Manu
